As Figure 12 A～Figure 12 C and shown in Figure 13, socket 50 has a plurality of sockets contacts 60 that form flat roughly rectangular-shaped socket body 51 and be configured to two row along the sidewall 54 of the length direction of socket body 51 by resin forming.From the front, at the central portion of socket body 51, be formed with roughly rectangular-shaped convex portion 53, between the sidewall 56 of the sidewall 54 of this convex portion 53 and length direction and Width, be formed with roughly rectangular insertion groove 52.

Socket contact 60 bends to the regulation shape by punch process etc. with the metal material of band shape and forms.In each socket contact 60, on the 1st end that faces in insertion groove 52, be formed with the 1st contact site 61 that contacts with plug bond post 80 (with reference to Figure 14 A～Figure 14 C and Figure 15).In addition, on the 2nd end of the socket contact 60 in the outside that is positioned at sidewall 54, be formed with 1st portion of terminal 62 of solder on the conductive pattern of circuit substrate.Each socket contact 60 is pressed into behind the resin forming of socket body 51.

In addition, as Figure 14 A～Figure 14 C and shown in Figure 15, plug 70 has a plurality of plug bond posts 80 that form flat roughly rectangular-shaped plug body 71 and be configured to two row along the sidewall 73 of the length direction of plug body 71 by resin forming.On plug body 71, with the position of convex portion 53 subtends of socket body 51 on, be formed with the roughly rectangular embeded slot 72 chimeric with this convex portion 53.On the two side 73 of plug body 71, the edge from the rear side (circuit substrate side) of plug body 71 is formed with protuberance 74 highlightedly with respect to sidewall 73 approximate vertical.In addition, on the wall of embeded slot 72 sides of sidewall 73, the impact that applies in order to be dispersed in conjunction with socket 50 and plug 70, be formed with everywhere with the convex portion 53 that is arranged on socket 50 on the chimeric mosaic process 75 of keyway 55.

Plug bond post 80 bends to the regulation shape by punch process etc. with the metal material of band shape and forms.Among each plug bond post 80,, be formed with the 2nd contact site 81 that contacts with the 1st contact site 61 of socket contact 60 along on the position of the outer surface of sidewall 73.In addition, from the end that protuberance 74 is given prominence to, be formed with 2nd portion of terminal 82 of solder on the conductive pattern of circuit substrate outwardly.Each plug bond post 80 is fixed on the plug body 71 integratedly by embedding moulding when the resin forming of plug body 71.

These sockets 50 and plug 70 by the 1st portion of terminal 62 of each socket contact 60 of solder and the 2nd portion of terminal 82 of each plug bond post 80, are assembled on the conductive pattern of circuit substrate respectively.If plug 70 is combined on the insertion groove 52 of socket 50, just can be relatively the convex portion 53 of socket 50 be entrenched in the embeded slot 72 of plug 70, the 1st contact site 61 of while socket contact 60 is strains on one side, contact on 2nd contact site 81 of plug bond post 80 on one side.Its result is electrically connected the circuit substrate of assembling socket 50 and the circuit substrate of assembled plug 70.

, at the connector that is used for small-sized electronic equipment such as pocket telephone, the spacing of socket contact 60 and plug bond post 80 for example is about 0.4mm, and is very narrow.In addition, for the miniaturization more of electronic equipment, require more small-sized connector.On the other hand, the size of the length direction of connector (orientation of socket contact 60 and plug bond post 80) is decided by the spacing or the radical of socket contact 60 and plug bond post 80.In addition, in order to ensure insulation distance, there is boundary in the spacing of dwindling socket contact 60 and plug bond post 80.Therefore, the miniaturization of connector can realize by the size that reduces its Width.

Generally, if on socket body 51, form plug body 71 chimeric insertion groove 52, will weaken the mechanical strength of socket body 51, easy deformation.In above-mentioned connector in the past, in order to improve the mechanical strength of socket body 51, convex portion 53 is set in the inboard of insertion groove 52, on plug body 71, be formed with simultaneously the embeded slot 72 chimeric with this convex portion 53.Therefore, connector in the past is unfavorable for that the size of the Width of socket body 51 and plug body 71 is only dwindled convex portion 53 sizes.

Same with described socket contact 20, because the gap of each plug bond post 40 is about 0.4mm and very narrow,, and plug body 31 is inserted in the model that resin forms therefore by root moulding plug bond post 40, be unpractical.Therefore, on a side of tabular metal mother metal, implement slit processing and formation broach shape, in addition with comb-tooth-like portion punch process established practice setting shape.In addition, will with the metal mother metal be pedestal be arranged in one row plug bond post 40 be inserted into simultaneously in the metal die for moulding of plug body 31.After one-body molded, cut off each plug bond post 40 of separation by embedding moulding at plug body 31 and plug bond post 40 from the metal mother metal.

In addition, on the both ends of the length direction of plug body 31, have useless wiring 40a, bury underground by embedding with plug body 31 one as the plug bond post of the function of terminal reinforcing fitting.Useless wiring 40a is formed on the metal mother metal identical with plug bond post 40, shown in Fig. 6 B, has the section configuration roughly the same with plug bond post 40.Wherein, be equivalent to the part of the 2nd contact site 41 of useless wiring 40a, be embedded in the both ends of plug body 31, do not expose on the surface.In addition, be equivalent to the fixed part 42a of the portion of terminal 42 of useless wiring 40a, with the roughly the same mode of full-size of the Width of plug body 31, it is shorter to be cut off the portion of terminal 42 that becomes than plug bond post 40.In addition, in the time of on the conductive pattern of portion of terminal 42 solders at circuit substrate of plug bond post 40, the fixed part 42a of the wiring 40a that also will give up solder simultaneously is on the surface of circuit substrate.Thus, can strengthen the constant intensity of plug body 31 on substrate.In addition, the fixed part 42a by useless wiring 40a in conjunction with socket 10 and plug 30 time, can alleviate the stress that imposes on plug bond post 40.

Socket 10 and plug 30 according to the connector 1 of present embodiment with as above constituting are assembled in respectively on two circuit substrates of mutual electrical connection.Particularly, on a side circuit substrate, for example on the conductive pattern of the circuit substrate of hard, the portion of terminal 23 of the socket contact 20 of solder socket 10, on the opposing party's circuit substrate, for example on the conductive pattern of FPC, the portion of terminal 42 of the plug bond post 40 of solder plug 30.In addition, if, just can be electrically connected the socket contact 20 of socket 10 and the plug bond post 40 of plug 30 respectively at the insertion groove 12 chimeric plugs 30 of socket 10.Simultaneously, by socket contact 20 and plug bond post 40, the conductive pattern of the circuit substrate of electrical connection hard and the conductive pattern of FPC.

At this, in conjunction with socket 10 and plug 30 time, the contact protuberance of socket contact 20 (free end of the 1st contact site) 24, the outer surface side of the bend 43 of roughly the fall U word shape of contact on the leading section that is arranged at plug bond post 40.But the radius of curvature of the bend 43 of plug bond post 40 forms that socket contact 20 at least can not be stuck in this bend and the radius of curvature that produces the minimum of buckling.Therefore, can prevent buckling of socket contact 20, the size that can dwindle the Width of plug 31 simultaneously can make every effort to realize the miniaturization of connector 1.In addition, the bend 43 of the word of falling U shape roughly is embedded in the plug body 31 in the mode of the side walls 33 that strides across recess 32, and bend 43 1 ends are fixed on the bottom surface of recess 32.Therefore, in conjunction with socket 10 and plug 30 time, even plug body 31 distortion, plug bond post 40 can not peeled off from the surface elevation of plug body 31 yet.

In addition, in the time of in the insertion groove 12 that plug 30 is entrenched in socket 10, the guiding that the inclined plane 15a of guide wall 15 that is arranged on the surrounding edge portion of insertion groove 12 can be used as plug 30 plays a role.Therefore, even more or less be offset, but plug 30 is entrenched in the insertion groove 12 with respect to the relative position of the plug 30 of socket 10.

Below, with reference to Fig. 7 A～Fig. 7 C and Fig. 8 A～Fig. 8 B, the process of assembled plug 30 on circuit substrate is described.When under the situation of assembled plug on the circuit substrate 30, make adsorption mouth 100 directly be connected on the adsorption plane of plug 30 and absorbed air, absorption keeps plug 30, adsorption mouth 100 is moved, and plug 30 is moved to assembling position.In Fig. 7 A, the position and the size of the suction inlet of symbol 101 expression adsorption mouth 100.From each figure as can be seen, the adsorption plane of adsorption mouth 100 abuts against on the adsorption plane of plug 30, promptly is entrenched on the 1st of a side in the insertion groove 12 of socket body 11.In addition, with respect to a suction inlet 101 of adsorption mouth 100,2～3 recesses 32 of subtend.In addition, each recess 32 is separated by next door 35 respectively.Therefore, with respect to the recess 32 of 1 suction inlet 101 subtend of adsorption mouth 100, form enclosure space by the bottom surface of two side 33, next door 35 and the recess 32 of the bearing surface of adsorption mouth 100, plug body 31.Therefore, if attract air in the above-mentioned enclosure space, just produce the negative pressure in the enclosure space, thereby make plug 30 attract to remain on adsorption mouth 100 from 1 suction inlet 101 of adsorption mouth 100.

In such cases, because the size that can make the length direction of recess 32 and Width is compared littler with the aperture of the suction inlet 101 of adsorption mouth 100 respectively, therefore compare with the example (with reference to Figure 14 A～14C and Figure 15) in the past on the bottom surface that adsorption mouth is connected to the embeded slot 72 that is arranged on the plug body 71, can dwindle the size of the Width of plug body 31.Its result can utilize adsorption mouth 100 absorption to keep plug 30, makes every effort to realize the miniaturization of plug 30 simultaneously.In addition, owing to be provided with a plurality of next doors between the plug bond post 40 of adjacency in the longitudinal direction, even therefore how many generation skews of the relative position of the adsorption plane of the suction inlet 101 of adsorption mouth 100 and plug body 31, also can make any next door 35 be configured in the both sides of suction inlet 101, prevent leakage of air reliably.In addition, the utility model is not limited to the formation of present embodiment, at least if with the both sides of the position of each suction inlet 101 subtend of adsorption mouth 100, the next door 35 that one by one disposes plug body 31 gets final product.

Below, with reference to Fig. 1, Fig. 9 A～Fig. 9 C, Figure 10 and Figure 11 A～Figure 11 C, the process of assembling socket 10 on circuit substrate is described.When under the situation of assembling socket 10 on the circuit substrate, not to utilize directly absorption maintenance socket 10 of adsorption mouth 100, but the adsorption cover 90 shown in Fig. 1 and Fig. 9 A～Fig. 9 C is installed on the socket body 11, and with the principal part 91 of adsorption mouth 100 absorption adsorption covers 90, keep socket 10 thus, and mobile adsorption mouth 100, socket 10 is moved to assembling position.

Adsorption cover 90 by sheet metal is implemented punch process and bending machining, forms the shape that can engage with socket body 11.Adsorption cover 90 has: the principal part 91 that essentially rectangular is tabular; Two pairs of wall portions 92 give prominence to length direction and with the direction of principal part 91 orthogonals respectively from the both ends of principal part 91; Holding section 93 is formed near the front end of each arm 92, and engages with socket body; Protuberance 94, the central portion from the both ends of the length direction of principal part 91 forms to the outside of length direction outstandingly, and is entrenched in the medial surface of guide wall 15 of the roughly コ font of socket body 11.

Size between two protuberances 94 of the length direction of principal part 91 is by the size formation roughly the same with the interval that is arranged on a pair of guide wall 15 on the socket body 11.In addition, the size of the Width of principal part 91 is by the size formation roughly the same with the size of the Width that is arranged on socket body 11.Then, under the state that adsorption cover 90 is fastened on the socket body 11, principal part 91 be placed on socket body 11 on the subtend face of plug 30 on.

Holding section 93, side-prominent to socket body 11 from the length direction both sides of each wall portion 92, the intermediate portion has pliability with to the outstanding mode bending of the side of socket body 11.In addition, near the lower end at the both ends on the length direction of the sidewall 13 of socket body 11, be formed with the engaging recessed part 16 of holding section 93 engagings of adsorption cover 90.In addition, in the bight of engaging recessed part 16 upsides, promptly with the bight of the subtend face of plug 30 and two side 13 on, the narrow more mode of width dimensions with the Width of past more upside socket body 11 is formed with inclined plane 17.

For adsorption cover 90 is installed on the socket 10, aim at the position on holding section 93 and inclined plane 17, and with adsorption cover 90 close socket body 11.If the holding section 93 of adsorption cover 90 is connected on socket body youngster's the inclined plane 17, then slide on inclined plane 17 in holding section 93, and holding section 93 is slowly crooked laterally.In addition, if holding section 93 surpasses inclined plane 17, then holding section 93 is fastened on engaging recessed part 16 because of elastic return arrives original shape.Its result, shown in Figure 10 and Figure 11 A～Figure 11 C, adsorption cover 90 is installed on the socket 10.At this moment, from the outstanding protuberance 94 of principal part 91, because chimeric, therefore can reduce the offset of the adsorption cover 90 in the plane parallel with principal part 91 with the medial surface of the guide wall 15 of コ word shape roughly.

Under the state that adsorption cover 90 is installed on the socket 10, by adsorption mouth 100 is connected to adsorption cover 90, and attract air, thereby adsorption cover 90 is adsorbed on the adsorption mouth 100 from suction inlet 101.In addition, mobile adsorption mouth 100, and make socket 10 be transplanted on assembling position.So, adsorb the adsorption cover 90 that keeps being installed on the socket 10 owing to can utilize adsorption mouth 100, therefore compare as adsorption plane routine (with reference to Figure 12 A～Figure 12 C and Figure 13) in the past with the leading section 53a of the convex portion 53 that establishes of will the insertion groove 52 of socket body 51 in, dashing forward, can dwindle the width dimensions of the Width of insertion groove 12.Its result, the size that can dwindle the Width of socket 10.

In addition, the interval of a pair of holding section 93 on the Width of socket body 11 is set at and is arranged on the roughly the same size in interval of the Width of the engaging recessed part 16 on the two side 13.At the state that adsorption cover 90 is installed on the socket 10, promptly holding section 93 is fastened under the state in the engaging recessed part 16, and holding section 93 is deflection laterally not, returns to original shape.Therefore, under the state in holding section 93 is fastened on engaging recessed part 16, compare with the situation that the state that strain takes place is fastened in the engaging recessed part 16 with hypothesis holding section 93, for example when the refluxing soft soldering material, even the socket body 11 of moulding product because of thermal expansion, also can reduce to impose on the stress of holding section 93 or socket body 11.Its result can prevent to take place crackle etc. on socket body 11.

In addition, owing near the both ends of the length direction of socket body 11, be provided with engaging recessed part 16, therefore can be combined in the holding section 93 of engaging recessed part 16 from fixed part 14a separator card with the fixed part 14a deviation post of terminal reinforcing fitting 14.Therefore, when the refluxing soft soldering material, the solder that can prevent fixed part 14a is attached on the holding section 93, and the situation that adsorption cover 90 is come off.In addition because adsorption cover 90, at least socket 10 is installed on the circuit substrate during in, be installed on the socket body 11, thus can be reduced in the conveying way of socket 10 or in the assembling dust enter possibility in the insertion groove 12.Its result can prevent dust attached on the socket contact 20, reduces the reliability that is electrically connected.And if to the direction traction adsorption cover 90 that separates from socket 10, holding section 93 is crooked laterally, so the engaging of holding section 93 and engaging recessed part 16 disengaging, can take off adsorption cover 90 from socket 10 easily.As mentioned above, under adsorption cover 90 is installed in state on the socket 10, because strain does not take place in holding section 93, return to original shape, the power of therefore drawing adsorption cover 90 is little also passable.So, can reduce to act on the stress of the portion of terminal 23 of the socket contact 20 of solder on circuit substrate.

Adsorption cover 90 forms by enforcement bending machining after adopting punch die stamping-out metallic plate, and it is shaped as the shape that is the line symmetry with respect to the central shaft of length direction.Therefore, an if distolateral shape of length direction, promptly prepare to be used for the punch die of the one-sided a pair of arm 92 of stamping-out, holding section 93 and protuberance 94, with the punch die of the pars intermedia that is used for the stamping-out length direction, just can make the corresponding adsorption cover 90 of socket 10 of all lengths different with the arrangement radical of socket contact 20.Particularly, suppose adsorption cover 90 is being made as under the situation of synthetic resin, need be corresponding to the assortment radical of socket contact 20, i.e. the size of the length direction of socket 10, and prepare independent shaping mould.In contrast, after by employing punch die stamping-out metallic plate, implement under the situation of bending machining formation adsorption cover 90, because the pars intermedia of the length direction of adsorption cover 90 is rectangular-shaped ground stamping-out only, so only need change the length of stamping-out by the punch die that utilizes pars intermedia to use, just can be easily different corresponding with the arrangement radical of socket contact 20.Therefore, can reduce the manufacturing cost of mould.

In addition, shown in Fig. 1, Fig. 2, Fig. 5 C and Fig. 6 A, in the 2nd contact site 41 of plug bond post 40, on the position of contact protuberance 24 sliding contacts of socket contact 20, be provided with projection 44 and recess 45.Particularly, shown in Fig. 1 and Fig. 5 C, projection 44 is formed on than the central authorities of the short transverse of plug bond post 40 slightly on the position by upside (with the opposition side of the outstanding side of portion of terminal 42).In the outside of projection 44, to be formed with inclined plane 44a the closer to the portion of terminal 42 outstanding big more modes of size.Recess 45 is the groove shapes that extend along the short transverse of plug bond post 40, and have with the Width of plug bond post 40, the section that is the direction of above-mentioned short transverse orthogonal is the roughly mode of V word shape, more towards two dark more inclined planes of the central portion degree of depth of Width.The width dimensions of the recess 45 on the Width of plug bond post 40 with the width dimensions greater than projection 44, and forms less than the mode of width dimensions of contact protuberance 24.In addition, the size and the position of the recess 45 on the short transverse of plug bond post 40 are arranged in the scope that the contact protuberance 24 of socket contact 20 slides on the 2nd contact site 41.

By formation like this, as shown in Figure 2, under the state of the inside of the insertion groove 12 that plug 30 is inserted into socket 10, contact protuberance 24 contact with the both sides of recess 45, and projection 44 compares and contacts the bottom surface side that protuberances 24 are positioned at insertion groove 12.In addition, in the process of the insertion groove 12 that plug 30 is inserted into socket 10, the both sides of the recess 45 of contact protuberance 24 Elastic Contact in the 2nd contact site 41 of plug bond post 40.In addition, in contact protuberance 24, the scope that contacts with projection 44 is not overlapping with the scope that the both sides with recess 45 contact.Therefore, even before in conjunction with socket 10 and plug 30, on the 2nd contact site 41 of the contact protuberance 24 of socket contact 20 or plug bond post 40, be attached with foreign matter, also can in the process that contact protuberance 24 moves on the surface of the 2nd contact site 41, foreign matter fallen in the recess 45.Therefore, if compare with the situation that recess 45 is not set on the 2nd contact site 41 of plug bond post 40, can be reduced in contact protuberance 24 and the 2nd contact site 41 between clip the possibility of foreign matter.That is,, can prevent the socket contact 20 that foreign matter causes and the loose contact of plug bond post 40 by on the 2nd contact site 41 of plug bond post 40, projection 44 and recess 45 being set.In addition, because contact protuberance 24 is in 2 contacts of the both sides of recess 45, so can improve the contact reliability of socket contact 20 and plug bond post 40.In addition, in the 2nd contact site 41 of plug bond post 40, owing in the sliding scale of contact protuberance 24, be provided with recess 45, therefore compare with recess 45 being arranged on the sliding scale locational situation in addition that contacts protuberance 24, make easily attached to the foreign matter on the contact protuberance 24 and drop into recess 45.

In addition, if apply power to pull the plug out of the socket 30 direction of the insertion groove 12 from socket 10, then the contact protuberance 24 of socket contact 20 touches on the projection 44 of plug bond post 40, is subjected to the resistance from projection 44.Therefore, vibrated etc. pull the plug out of the socket 30 advantage of also difficult insertion groove 12 from socket 10 even have connector 1.In addition, in the time of in the insertion groove 12 that plug 30 is inserted into socket 10, the contact protuberance 24 of socket contact 20 also touches on the projection 44 of plug bond post 40.But owing to be formed with inclined plane 44a to give prominence to the big more modes of size the closer to portion of terminal 42 on projection 44, the resistance when therefore plug 30 being inserted into insertion groove 12 is less than the resistance that pulled the plug out of the socket 30 o'clock from insertion groove 12.In addition, because in contact protuberance 24, the nonoverlapping mode of scope that contacts with both sides with recess 45 with the scope that contacts with projection 44 is set the position and the shape of recess 45, therefore when contact protuberance 24 slides on the surface of projection 44, the foreign matter of being released by contact protuberance 24 drops in the recess 45, can not be clipped in contact protuberance 24 and the 2nd contact site 41 between.

In addition, in the present embodiment, make the both sides of the recess 45 of contact protuberance 24 Elastic Contact on the 2nd contact site 41 of plug bond post 40 of socket contact 20, in the process that contact protuberance 24 slides on the surface of the 2nd contact site 41, foreign matter is dropped in the recess 45, can be reduced in the possibility of clamping foreign matter between contact protuberance 24 and the 2nd contact site 41 thus, improve contact reliability.But the shape and the contact condition thereof of the contact protuberance 24 of socket contact 20 and the 2nd contact site 41 of plug bond post 40 are not limited to the described formation of above-mentioned execution mode.For example, also can with the face of the 2nd contact site 41 contact that contacts protuberance 24 of socket contact 20, the pars intermedia that forms its Width than both ends more to the side-prominent shape (for example curve form) of the 2nd contact site 41 of plug bond post 40.In such cases, the pars intermedia of the Width of the contact protuberance 24 of socket contact 20 enters in the recess 45 that is arranged on the 2nd contact site 41, and 2 with recess 45 in two inclined planes or the edge of opening of recess 45 contact.Compare with the situation of plane contact mutually with the 2nd contact site 41 that contacts protuberance 24 and plug bond post 40 of socket contact 20, although it is complicated that the shape of socket contact 20 becomes, but dwindle the contact area of contact protuberance 24 and the 2nd contact site 41, and increase contact pressure.Its result discharges foreign matter easily between contact protuberance 24 and the 2nd contact site 41, improve the contact reliability of socket contact 20 and plug bond post 40.

In addition, in the bend 43 of plug bond post 40, at least compare the radius of curvature of the 2nd contact site 41 sides with the summit of bend 43 as long as set as follows, promptly when plug 30 is entrenched in the insertion groove 12 of socket body 11, the contact protuberance (free end) 24 of the deflection division (the 1st contact site) 22 of the roughly U word shape of socket contact 20, compare with the summit of the bend 43 of plug bond post 40 and to be easier to contact, and socket contact 20 is stuck in bend 43 and produces the scope of buckling and reach minimum in the 2nd contact site 41 sides.For example, in the bend 43 of plug bond post 40, summit from bend 43, make radius of curvature with the opposition side of the 2nd contact site 41, summit from bend 43, less than the radius of curvature of the 2nd contact site 41 sides, can further reduce the width dimensions of plug 30 thus, and then reduce the width dimensions of connector 1.

In addition, has recess 32 on the 1st of the side of plug body 31 in the insertion groove 12 that is fitted to socket body 11, recess 32 is separated by 2 next doors 35 at least, under the adsorption plane with the suction inlet 101 of adsorption mouth 100 and the mode adsorption mouth 100 of recess 32 subtends is connected to state on the 1st, be formed with 1 seal cavity as long as utilize the adsorption plane of the bottom surface of at least 2 next doors 35, recess 32 and adsorption mouth 100, can utilize adsorption mouth 100 to attract maintenance plugs 30 thus.
